Specification forming part of Letters Patent No. 207,524, dated August27, 1878 application filed July 20, 1878. I

To all whom it may concern:

. Be it known that I, W. L. HUssEY, of N ew Vienna, in the county ofClinton and State of Ohio, have invented anew and valuable I1n-'provelnent injFarm and Road Engines; and I do hereby declare that thefollowing is a full,

' ean-andexfact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon,

, Figure 1 of the drawings is a representa tion'of'a longitudinalvertical section of my improved road-engine. Fig. 2 is across-section ofthe same, and Fig. 3 is aview of the boiler and engine detached.

v This invention has relation to improvements ln'traction-engines foragricultural and. other purposes and the nature of the inventionconsists in the combination, with a boiler and engine,itsrearsupporting-frame, audits rear axle, having sprocket-wheels thereon,of a shaft actnated by said engine, and having sprocketv wheels 1ncorresponding positions with those of the axle, and endless chainspassing around said wheels. It also consists in a certain novelconstruction of the engine-frame and reach connectin g the same with thefore axle, whereby space 1s econonnzed and great strength is secured.

It also consists m a clutch of novel construction, arranged in the hubof the driving-wheels and actuated by rods in the axle, as will behereinafter more fully set forth.

In the accompanying drawings, the letter A designates an upright tubularboiler,'havingthe usnalsteam-Whistle a, throttle-valve lever I), andsafety-valve 17 upon its front and sides, within convenient reach of thedriver standing in a cab,;B. j This cab is provided with receptaclesforfifuel and water, and is secured to a strong-frame, G, rigidly boltedto the lower portionoffthe-boiler, and prevented from sagging by-meansofthe braces c 0, respectively connecting the-frontand rear portions ofsaid frame to theboiler. 0 represent pedestals dependingfromf'said framein rear of the boiler, and pr-OVidedwith axle-boxes not difi'eringcssentially from those commonly used on railroadcars, in which therearor driving axle of the mechanism has its bearings. This axle (desvignated by'the letter A) is hollow at its ends, but'solid at its centralportion, and carries at each end a driving-wheel,B. The wheels B aremade in two sections as to' their hubs, the

section'd supporting the spokes and tire, and

the section d being passed over the axle and secured to section dinanysnitable manner. These sections form with each other a recess, 0, theparallel vertical walls of which are ratcheted," as shown at vijandiif,and-in this recess is a pawl-key, e, extendingthrough the axle andsecuredgto th'e' 'outer; extremityof a metallic rod, f, in the bore oftheaxleafor'esaid, The inner end of thisyrod is'secure'd to a cross headworking in a slot, g,-'of: said }'a:' Ie,-and rigidly secured to -aring, 11'," embracingjthe same."

Rod f is consequently movable endwise, and

thekey-pawl may be engaged eitherwith the ratcheti or the ratchet i,at'plea'sure, or dis.

engaged from both, thus allowing-the wheels to turn or act independentlyof each other in.

turning or runningin a-cur've, orfallowing-the' movement of the engineto he 1n a forward or backward direction. The rods f are'operatedindependently byvmean's of thelevers D, whose .forked ends straddle theaxle and engage the rings g, and which have their fulcrums upon theframe and their power ends connected by i a spring, D. i

-E represents a strong metallic reach, bolted securely to the front ofthe .boiler'A, extending out'horizontally therefrom, and connect, ingthe boiler with the front axle. This reach has at its free end abracing, h, in which is journaled a cylindrical spindle, h, upon theupper end of an' angular support, F, the legs j of which straddle andreach below the axle F, and inclosebetween them a strong ellipticspring, G, the ends of which project beyond said support between thelegs j; Th s spring boiler in the'frame (1,011 a level with the rear.

axle. This shat't'has at each end a sprocket wheel, Z, connected withsimilar though lar'gerj sprocket-wheels l upon the rearaxle by means 2aem'sa a.

of endless chains J. These cylinders are pro- I, and having its bearingsin arms projectingfrom the boiler, is a shaft, I, carrying" a drum, L,and provided at one end with a gear, k, that meshes with a worm, Z uponan inclined shaft, S, arranged in suitablebearings at the side of theboiler, and terminating in rear at the cab. Rotary motion is imparted tothe shaft S, and consequently to the drumshaft, by means of a band-wheelor crank-arm, m.

V V represent Wire ropes or chains, secured each at one end to the frontaxle near the transporting-wheels N, and, being crossed, are thensecured to opposite ends of the drum, the one passing under and theother over the same, so that when the drum is rotated by the mechanismabove described, or by similar means, one of these ropes will be woundup and the other paid out, causing the front axle to turn on its centerand the road-engine to be directed right or left, as the case maybe.

In practice the drivingwheels have sufiiciently broad treads to supportthe weight of the boiler and engines.

In order to prevent the bearing of the support upon the reach frombinding when the road-engine is inmotion, I use a subsidiary reach, 1%,pivoted to vibrate vertically to the bottom of the boiler to allow thespring free movement, and to the front axle to allow it to turn freely.

P indicates a shaft arranged in suitable been in gs upon the reach, andcarrying at one end a pulley, p, and at the other-a sprocket-wheel, q.By unshipping the endless chains J and connecting one of thesprocket-wheels l-with the wheel qaforesaid, this mechanism is utilizedin drivingthrashing-maehines andother agricultural machinery.

What I clain'i'as new, and desire to secure by Letters Patent, is- J 1.The combinatiomwith the boilerA, of the .rear frame G, belted theretoand supported by the diverging braces c c,the cab B, supported by saidframe, and the reach E, bolted at one end to the boilecfront, andsupported by the fore axle at the other, substantially as specified.

2. The combination, with aboiler havingan engine upon its front, ofahorizontal frame, 0, bolted thereto, extending in rear, and supportinga cab, 13, and reach, E, secured to the front of the boiler above saidframe and supported by the fore axle, as set forth.

3. The combination, with the boilerA, rear frame 0, pedestals G, axle A,and drivingwheels B, of the reach E, having front hearing 7:, thesupport F, journaled therein, and having spaced legs straddling the,fore axle,

and a spring, l, between said axle and the support, substantiallyasspecified.

4. The combination, with the tubular-ended axle A, of rods f in saidaxle and movable endwise, the cross-head, and key-pawl c at each end ofsaid red, the driving-wheels B,

raving interior chamber (3, with opposite ratcheted walls i 6, rings9'', embracing the axle and secured to the cross-heads, the forkedlevers D, engaging said rings, and a spring, D, con' necting the ends ofsaid levers, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
